The EPS-16 Plus was a good sampler back when it came out. I remember it also had a solid keyboard feel which is always a plus. Just remember though that technology has moved on a lot in over a decade as I think it only sampled at a rate of 32Khz. How cheap is it? If it is VERY cheap ( $100 or less ) it may be a good deal. But buying a keyboard that old can always be a risk. Make sure all the keys and control buttons are working OK. Fixing an old keyboard can be difficult and expensive and sometimes parts ate simply impossible to find. Any repair work would probably cost more than you paid for the keyboard.
I think the most work will be setting up patches as you probably won't be able to find many nowadays so you will need to be a very keen sound programmer and sampler to get the most out of it. Thats what makes picking up an old DX7 easier, just that there are 1000s of sounds for it online. Setting up good samples from scratch is a long tedious task.
